A reinforcing steel bar protection method for a hydraulic type broken pile head is characterized by comprising the following steps that a, according to the number and the diameter of main reinforcements of a reinforcement cage, a plurality of hollow foam rods with the same number as the main reinforcements of the reinforcement cage and matched with the main reinforcements of the reinforcement cage in diameter are provided; b, a hollow foam rod is arranged on each reinforcing steel bar of a reinforcement cage main reinforcement over-poured concrete part at the top end of the reinforcement cage in a sleeving manner; c, firmly binding the connecting parts of the main reinforcements of the reinforcement cage and the lower parts of the hollow foam rods by using binding wires; and d, according to the standard requirement of a concrete reinforcement cage pile that the height of an over-pouring concrete part is at least 500 mm, in order to ensure that the position of a pile head reinforcement can be visually seen during concrete pouring, the length of the hollow foam rod is larger than the designed over-pouring requirement, and the reinforcement is conveniently protected when the pile head is separated by a hydraulic pile breaking machine. The reinforcing steel bar protection method for the hydraulic type broken pile head has the advantages that the foam hollow rod is simple in structure and convenient to use, direct contact between concrete and the pile head reinforcing steel bar is blocked, and it is guaranteed that the pile head reinforcing steel bar is not damaged when the pile head is broken.
一种液压式破桩头的钢筋保护方法，其特征在于包括以下步骤：a、根据钢筋笼主筋的数量及直径，提供若干与钢筋笼主筋同数量且直径配合的空心泡沫棒；b、在钢筋笼顶端的钢筋笼主筋超灌混凝土部分的每根钢筋上套入泡空心沫棒；c、将钢筋笼主筋与空心泡沫棒下部连接部位用扎丝绑扎牢固；d、根据混凝土钢筋笼桩规范要求超灌混凝土部分的高度最少为500mm，为保证砼浇筑能直观看到桩头钢筋位置，空心泡沫棒长度要大于设计超灌要求，便于液压破桩机将桩头分离时保护钢筋。本发明的液压式破桩头的钢筋保护方法具有泡空心沫棒结构简单、使用方便，阻断了混凝土与桩头钢筋的直接接触，保证破除桩头时桩头钢筋不被损坏的优点。
